This study found that people with ME/CFS and those with long COVID have similar problems with how their autonomic nervous system (the system that controls heart rate, blood pressure, and other automatic body functions) works. Researchers measured heart rate variability and blood pressure patterns in 34 ME/CFS patients, 29 long COVID patients, and 32 healthy controls. Both patient groups showed reduced autonomic function compared to healthy people, and these problems were linked to their fatigue—but not to depression or anxiety.
